Abstract (en)
[origin: EP2688159A2] The device has a laser (10) providing a beam of carrier wave signal. A set of amplifying fibers (30) provides optical waves. A separating unit (101) separates the wave signal into an initial probe beam (R01) and a signal beam (R3). An outputting unit outputs a probe beam (R1) and a reference beam (R2) so as to define an interferogram. A detector array (50) generates a digital hologram from the interferogram. A spatial phase modulator (60) is supplied with the hologram to diffract the signal beam at an input of the fibers, where modulator comprises refresh rate phase law characteristics.
